    <p>This has been asked before, but the answer that was accepted and worked for most people doesn't actually work 100% when you get into more complex tables.</p> <p>Check out the original post here: <a href="https://stackoverflow.com/questions/3432683/alternate-row-colors-when-you-have-rowspan/3432753#3432753">Alternate row colors when you have rowspan</a></p> <p>Nick Craver's answer is a great solution for tables ulitizing rowspans. But when you start splitting the columns with colspans, and more intricacies it seems to start breaking.</p> <p>I think the problem may be related to colspan's specifically, though I haven't been able to decipher the exact problem.</p> <p>I've put together a complex table (similar to the ones I'm trying to use) that demonstrates the issues in Nick Craver's original suggestion.</p> <p>Visit the jsFiddle page that Nick set up here: <a href="http://jsfiddle.net/nick_craver/JtPw5/" rel="nofollow noreferrer">http://jsfiddle.net/nick_craver/JtPw5/</a></p> <p>And paste this table into the HTML section to test it out:</p> <pre><code> &lt;table class="altRow" cellspacing="0" cellpadding="20"&gt; &lt;tbody&gt; &lt;tr&gt; &lt;td colspan="4"&gt;Simple Row - No Rowspan, just a colspan of 4&lt;/td&gt; &lt;/tr&gt; &lt;tr&gt; &lt;td colspan="4"&gt;Simple Row - No Rowspan, just a colspan of 4&lt;/td&gt; &lt;/tr&gt; &lt;tr&gt; &lt;td colspan="4"&gt;Simple Row - No Rowspan, just a colspan of 4&lt;/td&gt; &lt;/tr&gt; &lt;tr&gt; &lt;td rowspan="2"&gt; &lt;h4&gt;Rowspan of 2 - No issues here&lt;/h4&gt; &lt;/td&gt; &lt;td colspan="2"&gt; &lt;p&gt;ENERGY STAR 95 per cent AFUE or better with DC variable speed motor &lt;span class="star-icon-graphic"&gt;*&lt;/span&gt;&lt;/p&gt; &lt;/td&gt; &lt;td class="table-rebate-column"&gt;

&lt;/td&gt; &lt;/tr&gt; &lt;/tbody&gt; &lt;/table&gt; </code></pre> <p>As you can see it's not being displayed as it should. And it appears as though even simple rows don't work correctly when they have a colspan on them. </p> <p>I've tinkered around but can't seem to figure it out. Can anyone get this issue solved once and for all!? I'm sure it would benefit many web designers who have a project that involves a lot of tabular data.</p>

    1. COWhat is the logic you'd like to see, regarding alternating row colors among rowspans? It doesn't make much sense to me what you would like to even see as your ideal result, much less how to implement it generally with jquery. Could you elaborate on how you'd like to see it rendered?

    3. COSorry Jake, I thought it made sense. Instead of trying to re-explain it, it might be easier to refer you to [this thread](http://stackoverflow.com/questions/3432683/alternate-row-colors-when-you-have-rowspan) started by SO user 'leona'. She put together a decent example that should explains what I'm looking for.

A row detail

Detail views are divided into sections. All the information in the data section comes from columns in the selected row. The other sections display data from other, related rows.

Related data can be related in a to-one or a to-many fashion. Captions of data related in a to-many fashion link to a list view showing a filtered view of the table.

Try moving around until you find a non-empty to-many entry and click on the label to get to one. You can move back to the root by clicking on the database name in the header.
